Abstract
Eine Vorrichtung zur Kraftmessung weist eine elektromechanische Wägezelle (1) auf, die einen ring- oder scheibenförmigen Verformungskörper (2) hat. Ein Kraftaufnahmering (12) stützt sich über einen eine Gleitfläche bildenden ringförmigen Kugelflächenabschnitt (10) schwenkbar an einem Krafteinleitungsring (2) der Wägezelle (1) ab. Der Kugelflächenabschnitt (10) liegt in Höhe des ring- oder scheibenförmigen Verformungskörpers (2) der Wägezelle (1). Auf den Kraftaufnahmering (12) wirkende Seitenkräfte und Winkelbewegungen des Kraftaufnahmerings (12) verursachen kein die Messung der Wägezelle (1) störendes Biegemoment. A device for measuring force has an electromechanical load cell (1) which has an annular or disk-shaped deformation body (2). A force absorption ring (12) is pivotably supported on a force introduction ring (2) of the load cell (1) via an annular spherical surface section (10) forming a sliding surface. The spherical surface section (10) lies at the level of the annular or disk-shaped deformation body (2) of the load cell (1). Lateral forces acting on the force-absorbing ring (12) and angular movements of the force-absorbing ring (12) do not cause a bending moment which disturbs the measurement of the load cell (1).
